Spcification of Letters Patent No. 2.22.0, dated August 11, 1841.

To all ttf/mm. i! m (1)/ sm-wer): Il Be it known that T, Jo.\'.\s oixr, of 'est Ilemplield township` in the eonnt Of llaneaster and State ot' Pennsylvania. ha`\1e"in vented a new and lmprovell Mode ot' Separating Stunt trom Wheat: and l do herehy decla re that the followingisa full and exaet deseription. v

l malte a wooden e'vlinder of ahont two feet. six inehes in diameter. and ahont live feet long, the ends in part'. shut leaving..r a toleratde. laige opening' in the renter ll. for the admission ot air. in the renter of this e'vlinder l plare a sha ft'with arms through it, to whit-h the fans C. are attaehed. this l eall the windmill. and on the one end ol' the shaft is plaeed a wheel l). l'or the purpose ol turning the sha lit: on the opposite end is a crank E, whirh makes a sweep of about' t'our inehes -t'or the purpose ot' shakin, lr the shoe, and the tall hoard on whieh the grain falls from the shoe. 4ln the lower side ot' the e \linder of this windmill. as at 1. is an opening the whole lengt-h thereof, through which the wind passes out; a hoard l". is placed under this opening at an angle ot' about twenty tire degrees with the horixon to give the wind its proper dirertion to. and i on the t'all-hoard` ll.

t'raine (il. is made ol' seantlin;r about six and a halt t'eet long. and about. tive teet high and wide enough to reeeire the windmill, whieh is plaeed near one end oll this frame. lnnnediately under the hoard l" whieh gives the direction to the wind the fall-hoard ll. is suspended hv straps. l. attaehed one end to it. and the other to the top ot' the trame: the. side ot this tall-hoard next to the windmill is depressed at about l'onr degrees, with nearly the same depression of the. end next the whirl ot the windmill. A hopper l(` is plaeed i'n this l'raine with the shoe l.. whieh lets the grain down on the fall-hoard near to the eorner next; the Crank end ol` the windmill. .-\n nprighti shal't M, is placed with three projeetingl arms. one to reeeive the end of a strip of wood N to which the other end is attaehed to the eranlc. 'l`he seeond arm t). shakes the shoe, hy striking: it in passingr to and fro. and the third arm l. shakes the fall-hoard hein.;lr eonnet'ted hy a strip. 'hen the windmill is put in motion the vt'ull grains of wheat' will roll slowly down in the. dil'eetionol' the mostdepressed em'nerof the t'allhoard. while the mossenrrent ot' wind will roll the smut and other light grains from among' the good grains and hear it otl' at the far side ot the lall-hoard from the wind, the. steady enrrent ofair i'uilifht however roll some. ot the good grains otl' at the same side also. to prevent whieh. l pnt two ledges 1], erosswise on the fall-hoard whieh has` a tendenoxy to turn the l'ood rgrrains hat-lc against'. the wind in the proper direetion while the light eontinnes to be driven ott'.

'l`he advantages ot this machine overall others. are. that it separates the snuit grains without breaking: them. thus preventing` a portion of this light filth whieh when broken attaehes itself to the grains ot' which. and also `frees; the mill from the had smell and tilth hlaek dust' ot' the hroken smut: and lastly that itv requires so little foree to turn il that it will notl impede the progress of the mill.

What l el'aim as in v invention, and desire to seenre hy Letters Patent.. is-

'l`he manner in whieh the fall-hoard ll. the hopper K.. the shoe l.. and hoard l"` t'or direetin r the ein-rent of air upon the ,qi-ain and eoinl inin; Y togetlier--tluitis to say the arranging the hopper and shoey over the lower end ol the wind hoard l". and ineliningl the. fall-hoard l'l. on its inner sido and one end so as to allow' the .grain to eross the enrrent' ot' air the whole heing eonstrneted and opeiatiue' substantially as set forth.
